LEWIS F. BETTS, OF CHICAGO, ILL., AS SIGNOR OF ONE-HALF OF HIS RIGHT TOJOSEPH S. DENNIS AND HENRY N. WHEELER, OF SAME PLACE.

IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 185,067, dated December5, 1876; application filed November 6, 1876.

To all whom it may concern:

Be it known that I, LEWIS F. BETTS, of Chicago, in the county of Cookand State of Illinois, have invented certain Improvements inWashing-hilachines, of which the following is a specification:

1n the accompanying drawing, which forms part of this specification,Figure 1, is a side elevation of one of my improved washingmachines.Fig. 2 is a plan view of'the same. Fig. 3 is an end view of the same,and Fig. 4 is a section on line a: w of Fig. 1.

Like letters of reference denote like parts wherever used in the severalfigures.

In the said drawing, A represents a central corrugated roller,surmounted by a jacket of small rollers, B B, between which and the saidcentral roller the clothes to be washed are passed to and fro. G O arewooden headblocks, one at each end of the rolling parts. These blocksare united to each other below by the bars D D, which project toward thesides of the tub, and carry at one end a toothed metalsegment,E,andatthe other pass through a cross bar, F, suitably beveled at the ends tofit the curve of the tub. Thebars D pass loosely through this cross-barF, and are held therein by set-screwsj', affording a means of adjustingthe frame work to difl'erent size tubs. A spring-point, d, at each endof the cross-bar F serves to prevent the frame-work from slipping about.The said point, when the machine is in place, sets out into the wood ofthe tub.

G G are metal castings, four of which are used in the construction ofeach machine. These castings are all alike, and consequently the partsare interchangeable, and but one pattern is necessary. This casting hasa projection, g, at the bottom, by which it is secured to the woodenhead-piece O, and is pierced centrally at this lower part for thepassage, and to form a bearing for the shaft a of the large roller A.Above this lower portion the casting spreads into a segmental orfan-like form, to afford a bearing for the pivots of the small rollers.A flange, h, extends around the edges, so that when two castings arebrought together upon one of the wooden head-pieces O a hollow space isformed above the wood, for the reception of the pressure-springsinserted above the small roller pivots b. A radial slot, 1', is formedin' the casting for each pivot b, and a radial flange, m, upon the innerface at each side of the slot, so that the spiral spring M above eachsmall roller pivot shall be held upright in place. A perforated lug, N,at the top of each cast-ing, allows the insertion of the ends of ahandle, N, which serves also as a tie or brace between the heads. H isthe crank-handle, by which the large roller is turned and the machineoperated.

Each small roller, it will be seen, is independent of every other one,and delivers its yielding pressure upon the large central roller fromthe force of its own pair of independent springs, uninfluenced by anduninfluencing the others, and this yielding pressure is applied at eachend alike and independent of the other end. i

A yielding pressure at all times alike, and at no point or timeexceeding the force of a single pair of springs, is thus distributedequally throughout the jacket of small rollers. This renders the workingof the apparatus smooth and even, and the same, whether the materialoperated on between the rollers is thick or thin.

In constructing the machine, the peculiar form and similarity of thecastings render the assembling of the parts very simple and easy, nofitting or forcing being requisite. The castings are affixed a pair toeach wooden block, the springs being inserted in place. The blocks andcastings are then brought up to the rollers, and the whole securedtogether, in

the manner clearly above indicated.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The casting G, four of which are used in the construction of eachmachine, said casting being formed with radial slots for the receptionof the small roller pivots, having radial flanges to form boxing for thesprings, and having a circumferential flange to inclose the hollow spacewhen two castings are brought together face to face, substantially asspecified. V

2. The combination, with the rollers and Wooden head-blocks, of the twopairs of castings Gr, mounted on the head-blocks, and containing theseveral springs, substantially as 3. The combination of the largecentral roller and the jacket of small sui'mounting rollers, the latterhaving each a pair'of in(lepeudent springs, one as each .end, overlyingthe pivots, and incased in the head-pieces, substantially as specified.
